William,
Thanks for clarifying some of the details of pexpect. I do really want to
understand this because I am starting to use the notebook more and currently
IPython's parallel stuff works fine (there are a few things that need to be

Sounds like a great idea to me to de-couple the notebook from sage.
Appengine is not the only option though (but maybe the cheapest at
least for now), you could probably use an Amazon EC2 instance just as
easily (and with some more facilities at your disposal, having a
virtual server running).

One of the problems I've had with the notebook implementation is that

hard to convert my work from Jinja templates to Django templates, or
